Mathews, a combat engineer with 38 Canadian Brigade Group in Winnipeg, came into the spotlight last week after a Winnipeg Free Press story linked him to a neo-Nazi group called The Base. The allegation further inflamed ongoing concerns about the presence of hate groups and right-wing extremists in the Canadian Forces.

Mathews had requested earlier this year to leave the military.

On Tuesday, the Defence Department said his request for voluntary release was to be fast-tracked and finalized in the coming weeks. In the meantime, he would not be allowed to participate in military activities in any form or return to work.

“This action was deemed necessary considering the seriousness of the allegations and the risk to unit morale and cohesion,” the department said in an email.

Chief of defence staff Gen. Jonathan Vance said last week that the military “did not miss” Mathews’s alleged links to neo-Nazism, as his commanding officers had started looking into the matter back in April.

Soon after, Mathews applied to leave the Armed Forces, Vance said, even as military intelligence officers began a formal investigation.

“It is incumbent of our leaders to know their soldiers, and to take measures when they have acted in a manner that is not aligned with our beliefs and culture of respect for all people,” she said in an email.

“We have taken decisive action, and we will continue to exert full energy in removing those from our ranks who harbour extremist ideologies.”

The RCMP are reportedly conducting their own investigation, but have only said that officers raided a house in Beausejour, about 60 kilometres east of Winnipeg, last week and seized a number of weapons.

RCMP said they are looking for Mathews as a missing person. There is no warrant for his arrest nor any charges pending against him.

Defence Minister Harjit Sajjan has asked Canada’s military ombudsman to investigate racism in the Canadian Forces following several high-profile events and a report linking service members to right-wing extremists and hate groups.

Sailors associated with the Proud Boys disrupted a Mi’kmaq ceremony in Halifax in 2017. There have also been media reports of other members associating with neo-Nazi groups such as the Atomwaffen Division.

A military intelligence report last year said officials were aware of 30 active service members who were part of a hate group or had made statements that were discriminatory or racist.
